[0040] The present invention provides the following embodiments:

[0041] Embodiment 1

[0042] The embodiment of the present invention provides a box-type transformer and system, as Figures 1-7 shown, including: a transformer box body 1, a transformer 11 is installed in the transformer box body 1, an installation component 6 is provided on the side surface of the transformer box body 1, air-cooling components 2 are provided on the left and right side surfaces of the transformer box body 1, and a liquid-cooling component 4 is provided on the top surface of the transformer box body 1;

[0043] It further includes a temperature control component, and the temperature control component is used to monitor and adjust the temperature inside the transformer box body 1.

[0044] The working principle and beneficial effects of the above technical solution are as follows: The transformer box body 1 is installed on the support structure through the installation component 6. A transformer 11 is installed in the transformer box body 1 and is infiltrated with oil. When the transformer 11 in the transformer box body 1 is connected to a load, the air-cooling component 2 performs air cooling on the outside of the transformer box body 1, and cools the oil through external air flow exchange. The liquid-cooling component 4 performs liquid cooling on the inside of the transformer box body 1, and reduces the temperature by directly exchanging heat with the oil. The temperature control component monitors the temperature inside the transformer box body 1 and manages and controls the air-cooling component 2 and the liquid-cooling component 4 according to the temperature situation;

[0045] In the present invention, the installation component 6 is used to mount the transformer box body 1. This design can ensure the stability of the wall-mounted transformer box body 1, avoid the overturning of the transformer box body 1 caused by wall mounting, and can reduce the vibration transmitted by the support structure to the transformer box body 1, avoiding affecting the transformer 11. The design of the air-cooling component 2 ensures that the transformer box body 1 can effectively utilize the wind force of the external environment for cooling, which not only saves energy but also ensures the cooling efficiency of the transformer box body 1, and can adjust the opening condition of the air-cooling component 2 according to the temperature of the transformer box body 1 to ensure that the transformer 11 operates within a suitable temperature range. The design of the liquid-cooling component 4 ensures that the transformer 11 can perform active refrigeration, can directly cool the temperature of the oil in the transformer box body 1 quickly, and avoid insufficient cooling of the transformer 11 under high load conditions. The design of the temperature control component ensures that the transformer 11 has a high temperature adjustment ability, and cools the transformer 11 by reasonably adjusting air cooling and liquid cooling, which not only ensures efficient refrigeration but also ensures the best working efficiency of the transformer 11 within a suitable temperature range.

[0046] Embodiment 2

[0047] On the basis of Embodiment 1, the air-cooling component 2 includes air-cooling channels 21. A plurality of air-cooling channels 21 are fixedly connected to the left and right side walls of the transformer box body 1. The bottoms of the plurality of air-cooling channels 21 are connected to the air chamber 22. The air chamber 22 is bolted to the bottom of the transformer box body 1. The tops of the plurality of air-cooling channels 21 are respectively connected to two transverse air ducts 23. The two transverse air ducts 23 are symmetrically and fixedly connected to the tops of the left and right sides of the transformer box body 1. Exhaust fans 24 are bolted to both ends of the two transverse air ducts 23. A filter screen 25 is penetrated and slidably connected to the air chamber 22. Opening structures 3 are provided on the front and rear side surfaces of the air chamber 22.

[0048] The opening structure 3 includes an opening window 31 which is arranged on the side of the air chamber 22. A number of opening baffles 32 are arranged in the opening window 31. The a number of opening baffles 32 cooperate with each other. Both ends of the a number of opening baffles 32 are bolted with fixed clamping seats 33. The fixed clamping seats 33 are rotatably connected to the air chamber 22. The a number of fixed clamping seats 33 are hinge-connected through a linkage plate 34. A traction rod 35 is hinge-connected to the linkage plate 34. The other end of the traction rod 35 is hinge-connected to the working end of an electric telescopic rod 36. The electric telescopic rod 36 is hinge-connected to the side wall of the air chamber 22.

[0049] The working principle and beneficial effects of the above technical solution are as follows: When the transformer 11 is air-cooled, the electric telescopic rod 36 expands and contracts, driving the traction rod 35 to displace, so that the traction rod 35 pulls the linkage rod downward. The linkage rod then drives the a number of fixed clamping seats 33 to rotate. When the fixed clamping seats 33 rotate, the opening baffles 32 rotate synchronously. An interval is generated between the a number of opening baffles 32. As the rotation angle of the fixed clamping seats 33 increases, the interval between the opening baffles 32 becomes larger. Until the opening baffles 32 rotate to 90° for the maximum interval. After the cold air flow enters the air chamber 22 from the opening baffles 32, the filter screen 25 filters the cold air flow. Subsequently, the cold air flow enters a number of air-cooling channels 21 on both sides of the air chamber 22. The cold air flow exchanges heat with the transformer box body 1 when passing through the air-cooling channels 21. Subsequently, the cold air flow converges into the transverse air duct 23 again and finally flows out from both ends of the transverse air duct 23. When there is no cold air flow in the external environment, the exhaust fan 24 starts, so that a number of air-cooling channels 21 suck air from the air chamber 22 for cooling;

[0050] The present invention uses cold air flow to cool the transformer box body 1. This design can ensure the passive cooling of the transformer box body 1. And in cooperation with the air chamber 22, it can make the cold air flow circulate stably and continuously cool the transformer box body 1. Moreover, the design of the exhaust air chamber 22 can extract air independently when the cold air flow does not flow, ensuring the forced operation of the air-cooling component 2. At the same time, the design of the opening baffles 32 can adjust the air intake volume in the air chamber 22, thereby accurately controlling the air-cooling efficiency of the air-cooling component 2.

[0051] Embodiment 3

[0052] On the basis of Embodiment 1, the liquid cooling component 4 includes cooling and heat dissipation exhaust pipes 41. The two cooling and heat dissipation exhaust pipes 41 are respectively arranged on both sides of the transformer 11. The output ends of the two cooling and heat dissipation exhaust pipes 41 are respectively connected to the two liquid cooling discharge pipes 42. The two liquid cooling discharge pipes 42 penetrate and are fixedly connected to the transformer box 1. The other ends of the two liquid cooling discharge pipes 42 are both connected to the input end of the compressor 43. The output end of the compressor 43 is connected to a cooling structure 5. The output end of the cooling structure 5 is connected to two liquid cooling return pipes 44. The two liquid cooling return pipes 44 penetrate and are fixedly connected to the transformer box 1. The other ends of the two liquid cooling return pipes 44 are respectively connected to the input ends of the two cooling and heat dissipation exhaust pipes 41. The compressor 43 is bolted to the top of the transformer box 1.

[0053] The cooling structure 5 includes a heat dissipation cylinder 51. The heat dissipation cylinder 51 is bolted to the top of the transformer box 1. Condensing pipes 52 are arranged in the heat dissipation cylinder 51. The input ends of the condensing pipes 52 are all connected to the compressor 43. The output ends of the condensing pipes 52 are all connected to the two liquid cooling return pipes 44 through expansion valves 53. Heat dissipation fans 54 are bolted to both ends of the heat dissipation cylinder 51.

[0054] The beneficial effects of the above technical solution are as follows: When it is necessary to perform liquid cooling on the transformer box 1, the compressor 43 starts to suck the liquid cooling discharge pipe 42, so that the liquid cooling medium after heat exchange with the oil in the transformer box 1 in the cooling and heat dissipation exhaust pipe 41 enters the compressor 43 for compression and heat dissipation. Subsequently, the liquid cooling medium enters the condensing pipe 52. The heat dissipation fans 54 at both ends of the heat dissipation cylinder 51 start to cool the condensing pipe 52. After sufficient cooling, the liquid cooling medium is depressurized and dissipated through the expansion valve 53. Finally, the liquid cooling medium enters the cooling and heat dissipation exhaust pipe 41 again through the liquid cooling return pipe 44 to exchange heat with the oil in the transformer box 1;

[0055] The present invention uses the cooling and heat dissipation exhaust pipe 41 to dissipate heat from the oil in the transformer box 1. This design can use the liquid cooling medium to quickly cool the oil, which can meet the heat dissipation of the transformer 11 under high load working conditions, ensure the stable operation of the transformer 11. At the same time, the design of the heat dissipation cylinder 51 and the heat dissipation fans 54 can cool the liquid cooling medium. This design can help the liquid cooling medium to be quickly cooled and ensure the cooling efficiency of the liquid cooling component 4.

[0056] Embodiment 4

[0057] On the basis of Example 1, the mounting assembly 6 includes a mounting plate 61, and a fixed hook claw 62 is symmetrically fixedly connected to the bottom of the mounting plate 61, and a floating hook claw 63 is provided above the fixed hook claw 62. The floating hook claw 63 is installed on the mounting plate 61 through a fastening bolt 64, and the fastening bolt 64 is slidably connected in a sliding groove 65. The sliding groove 65 is provided on the mounting plate 61, and a steel frame 66 is nested and connected between the fixed hook claw 62 and the floating hook claw 63. Leveling bolts 67 are passed through and threadedly connected on the two fixed hook claws 62. The leveling bolts 67 and the steel frame 66 abut against each other, and the steel frame 66 is connected to the transformer box 1 through a shock absorbing structure 7.

[0058] The shock absorbing structure 7 includes a shock absorbing cross bar 71, two shock absorbing cross bars 71 are bolted to the steel frame 66, the transformer box 1 is sleeved on the two shock absorbing cross bars 71, compression elastic parts 72 are provided on both sides of the transformer box 1 and between the steel frame 66, the compression elastic parts 72 are sleeved on the shock absorbing cross bars 71, and two compression elastic parts 73 are provided between the transformer box 1 and the mounting plate 61, and the two compression elastic parts 73 are symmetrical up and down.

[0059] The beneficial effects of the above technical solution are as follows: when the transformer box 1 is wall-mounted, the mounting plate 61 is bolted to the supporting structure, the fixed hook 62 on the mounting plate 61 supports the bottom of the steel frame 66, and the floating hook 63 slides in the sliding groove 65 through the fastening bolt 64 to achieve the limit and fixation of the top of the steel frame 66. When the steel frame 66 is tilted, the steel frame 66 is leveled by rotating the leveling bolts. At the same time, the shock-absorbing cross bar 71 on the steel frame 66 is connected to the transformer box 1 to suspend it. When the supporting structure vibrates left and right, the transformer box 1 squeezes and compresses the elastic member 1 72, and when the supporting structure vibrates front and back, the transformer box 1 squeezes and compresses the elastic member 2 73, thereby achieving vibration buffering;

[0060] The present invention utilizes fixed hooks 62 and floating hooks 63 to fix the steel frame 66 of the transformer box 1. This design can make the steel frame 66 easy to install and can be adjusted in time according to the state of the steel frame 66 to ensure the stability of the steel frame 66 fixation. The design of the leveling bolts can ensure the levelness of the steel frame 66 to prevent the steel frame 66 from tipping over and causing the transformer box 1 to tilt. At the same time, the design of the shock-absorbing cross bar 71 and the compression elastic member 1 72 can reduce the vibration of the transformer box 1 in the left and right directions, and the compression elastic member 2 73 can reduce the vibration of the transformer box 1 in the front and back directions.

[0062] Based on Example 1, the temperature control component includes a control module, a data processing module, a detection module and an execution module, and the detection module includes:

[0063] Temperature sensor: used to check the temperature inside the transformer housing 1, and is set inside the transformer housing 1;

[0064] Temperature difference sensor one: used to detect the temperature difference at both ends of a single air-cooled channel 21, and is set on the air-cooled channel 21;

[0065] Temperature difference sensor two: used to detect the temperature difference between the liquid-cooled discharge pipe 42 and the liquid-cooled return pipe 44, and is set on the transformer housing 1;

[0066] Wind speed sensor: used to detect the external environmental wind speed, and is set on the transformer housing 1;

[0067] Power sensor: used to detect the power of the transformer 11, and is set on the transformer 11;

[0068] Rotation speed sensor: used to detect the rotation speed of the exhaust fan 24, and is set on the exhaust fan 24;

[0069] Flow sensor: used to detect the flow rate inside a single cooling radiator pipe 41, and is set on the cooling radiator pipe 41;

[0070] The detection module is electrically connected to the data processing module, and the control module is electrically connected to the data processing module and the execution module. The control module controls the operation of the execution module based on the data result of the data processing module.

[0071] The control module controls the execution module based on the data result of the data processing module, including the following steps:

[0072] Step one: Based on the detection values of the temperature sensor, temperature difference sensor one, temperature difference sensor two, wind speed sensor, power sensor, rotation speed sensor, and flow sensor, calculate the heat dissipation efficiency coefficient D of the transformer 11 e :

[0073] Where: D e is the heat dissipation efficiency coefficient of the transformer 11, ξ is the air-cooled loss coefficient, N is the number of air-cooled channels 21, S is the area of the air-cooled channel 21, ΔT 1 is the detection value of the temperature difference sensor one, ρ 1 is the density of air, c 1 is the specific heat coefficient of air, t 1 is the passing time of cold air in the air-cooled channel 21, V is the detection value of the wind speed sensor, D is the diameter of the exhaust fan 24, n is the detection value of the rotation speed sensor, μ is the liquid-cooled loss coefficient, c 2 is the specific heat capacity coefficient of the liquid-cooled medium, Q is the detection value of the flow sensor, t 2 is the passing time of the liquid-cooled medium through the cooling radiator pipe 41, ρ 2is the density of the liquid cooling medium, ΔT 2 is the detected value of the temperature difference sensor two, c 3 is the specific heat capacity coefficient of the oil, m is the mass of the oil, T is the detected value of the temperature sensor, W is the detected value of the power sensor, and η is the power heat generation coefficient;

[0074] Step 2: The data processing module compares D e and D e0 , when D e < D e0 , calculate the adjustment coefficient C. When D e ≥ D e0 , no processing is performed;

[0075] Where: C is the adjustment coefficient, D e0 is the lowest heat dissipation efficiency coefficient;

[0076] Step 3: The control module obtains the adjustment parameters of liquid cooling and air cooling according to the adjustment coefficient, and the control module drives the execution module to control the adjustment of air cooling and liquid cooling;

[0077] The adjustment coefficient is used to adjust the opening parameter of the air cooling component 2 and the rotation speed parameter of the exhaust fan 24 in the transformer 11, as well as the flow parameter of the liquid cooling component 4 based on the adjustment coefficient.

[0078] The beneficial effects of the above technical solution are: Since the temperature of the transformer 11 is affected by the heat dissipation of the oil and the power of the transformer, when the power of the transformer 11 suddenly changes, its corresponding heat generation changes synchronously, and the heat generation causes the accumulation of heat. If the working states of air cooling and liquid cooling remain constant, it will cause the accumulation of heat in the transformer 11. Therefore, by monitoring the temperature and power changes inside the transformer, the working states of air cooling and liquid cooling are adjusted in real time;

[0079] The present invention uses a control module, a data processing module, a detection module, and an execution module to monitor and calculate the heat dissipation efficiency of the transformer 11, and determines whether the current air cooling and liquid cooling match the working state of the transformer 11 by judging the heat dissipation efficiency, and makes corresponding adjustments. This design can ensure the flexible adjustment of heat dissipation in the transformer 11, and avoid the accumulation or excessive heat dissipation of the transformer 11.

The present invention uses the frame-type tower 8 to mount the transformer box body 1, and this design can ensure that the transformer box body 1 does not occupy land and reduces the construction cost.
